crutschowCan you measure the DC and AC voltage coming from the speaker wires? Does this go to zero when the alarm is off?
Is this alarm a tone or from a radio?
If you can use a separate battery then you can likely use a transistor amp to turn on the motor.
when alarm is off, there is not voltage (0 dc voltage) across speaker wires.
when alarm is on, it start beep, then another type of beep, and then last type (loudest) type of beep.
when alarm starts, the voltage starts increasing and continuously fluctuating.
the voltage is different when speaker is connected, and when speaker is not conected.
when alarm is on and mulimeter in connected to terminals then if i put fingers on the terminals of multimeter, the voltage rises to around 0.75 , i don't know why
